结合图11-图12所示，是本发明的雾化芯3，由多孔陶瓷制得，可以理解的是，制得雾化芯3的材料还可以是发泡金属、多孔玻璃或硬质玻纤管等具有微孔毛细效应的多孔材料。
该雾化芯3包括雾化芯主体31，其为多孔结构，雾化芯主体31设有用于吸取并暂时存储雾化液的进液槽，该进液槽可以包括至少两个，如包括第一进液槽311以及第二进液槽312，优选地，进液槽的侧壁突出雾化芯主体31的上表面且向上延伸设置，由此可以增大储液容积以及吸液面积。在本实施例中，该雾化芯3设于第一基座21中，且进液槽与过液孔对应设置，如第一进液槽311与第一过液孔22对应设置，第二进液槽312与第二过液孔23对应设置。

结合图13所示，在一些实施例中，雾化芯主体31的底面中部设有向下延伸的凸起316，凸起316沿雾化芯主体31宽度方向延伸以与凹槽的下侧缘连接，强制引导气流往雾化芯主体31侧边流动，即导向凹槽流出，防止气流直接从进气孔流动到出气孔11，从而增加带出的烟雾量。
雾化芯3还包括发热体32，其设于雾化芯主体31的第二表面，用于加热经由雾化芯主体31传导的雾化液而生成气溶胶。
结合图14-图16所示，在另一实施例中，该雾化芯3’包括雾化芯主体31’，其为非多孔结构，雾化芯主体31’设有用于吸取并暂时存储雾化液的进液槽，该进液槽可以包括至少两个，如包括第一进液槽311’以及第二进液槽312’，优选地，进液槽的侧壁突出雾化芯主体31的上表面且向上延伸设置，由此可以增大储液容积。在本实施例中，该雾化芯3’设于第一基座21中，且进液槽与过液孔对应设置，如第一进液槽311’与第一过液孔22对应设置，第二进液槽312’与第二过液孔23对应设置。
该雾化芯主体31’长度方向的两端侧面向外延伸形成台阶部313’，优选地，第一基座21的长度方向两侧的内壁设有限位槽26，台阶部313’卡合于限位槽26内。限位槽26包裹住台阶部313’，提高密封性，防止漏油。当然，该第一基座21的内壁也可以是设有整段环状的限位槽26，而台阶部313’也可以是环绕设于雾化芯主体31’的周向侧面，提高整体的包裹性。
雾化芯主体31’长度方向的中部至少一侧向中心凹设形成凹槽，凹槽与第一基座21的内侧壁相配合形成气流腔，该凹槽可以是对称设置的两个，如包括第一凹槽314’以及第二凹槽315’，结合图10所示，对应的，第一基座21的内侧壁与凹槽对应可以设有槽27，该凹槽与槽27尺寸可以调整，由此可以调整气流腔的尺寸。
在一些实施例中，雾化芯主体31’的底面中部设有向下延伸的凸起，凸起沿雾化芯主体31’宽度方向延伸以与凹槽的下侧缘连接，强制引导气流往雾化芯主体31’侧边流动，即导向凹槽流出，防止气流直接从进气孔流动到出气孔11，从而增加带出的烟雾量。
优选地，进液槽贯穿雾化芯主体31’的上下表面设置，且进液槽通腔内设有吸液件，如设置在第一进液槽311’的通腔中的第一该吸液件316’以及设置在第二进液槽312’的通腔中的第一该吸液件317’，该吸液件可以是吸液棉，或者其他实现吸液渗液功能的材质。该吸液件设置在进液槽通腔内的底部，以与发热体32’的发热轨迹距离最近，便于加速雾化液的雾化。
雾化芯3’还包括发热体32’，其设于雾化芯主体31’的底面，用于加热经由雾化芯主体31’传导的雾化液而生成气溶胶。该发热体32’的发热部与吸液件对应设置。
结合图17-图20所示，发热体32’与发热体32的结构形式可以相同，这里以发热体32为例进行解释说明，该发热体32通电后加热存储于雾化芯主体31中的雾化液，从而产生可供用户直接抽吸的气溶胶。发热体32为片状的发热网，发热体32贴合固定于雾化芯主体31的雾化面上。该发热体32可以是弯折形成盘状的发热丝或者是格栅状的发热片，该发热体32可以与雾化芯主体31烧结成一体结构以附着在上述雾化面上。在一些实施例中，上述发热体32还可以是形成在雾化芯主体31的底面（雾化面）上的发热线路、发热轨迹、发热涂层或发热膜等。其结构形状可以有多样，可根据需求进行选择。上述的发热网、发热丝、发热片、发热线路、发热轨迹、发热涂层或发热膜等与进液槽对应设置，使得进液槽和发热体32的距离最近，用于雾化液如烟油等快速到达发热轨迹雾化。
发热体32的材料可以是具有适当阻抗的金属材料、金属合金、石墨、碳、导电陶瓷或其它陶瓷材料和金属材料的复合材料。适当阻抗的金属或合金材料包括镍、钴、锆、钛、镍合金、钴合金、锆合金、钛合金、镍铬合金、镍铁合金、铁铬合金、铁铬铝合金、钛合金、铁锰铝基合金或不锈钢等中的至少一种。

当发热体32通电后，由于第一发热部322、连接部325和第二发热部324三者之间为串联的关系，故通过其三者的电流相等，由于连接部325的电阻较小，故连接部325的发热功率小于第一发热部322的发热功率、连接部325的发热功率也小于第二发热部324的发热功率，进而使得在相同的时间内，连接部325上产生的热量较小，避免了发热体32的中间温度过高而出现糊味的情形，保证了良好的用户体验。当然，该第一发热部322、连接部325和第二发热部324三者之间也可以是其他连接关系，由此可以调整发热功率。这里不做具体限定。
优选地，第一发热部322与第一进液槽311相对设置，第二发热部324与第二进液槽312相对设置。
优选地，发热体32还包括与第一导电部321连接的第一钩爪部326，以及与第二导电部323连接的第二钩爪部327，第一钩爪部326与第二钩爪部327嵌设于雾化芯主体31中，该第一钩爪部326与第二钩爪部327可以是L型结构，其提高发热体32的固定稳定性。可以理解的，该发热体32可以与雾化芯主体31为一体结构，也可以是采用印刷工艺印刷在雾化芯主体31上，其结构可以有多种，这里不足具体限定。
结合图21-图22所示，该隔离件4收容于雾化套1内，其与密封件2相配合以围设住雾化芯3，其可由硬质的塑胶材料制得，譬如酚醛塑料、聚氨酯塑料、环氧塑料、不饱和聚酯塑料、呋喃塑料、有机硅树脂、丙烯基树脂等及其改性树脂为机体制备而成。

优选地，侧板52的外侧面设有限位凸点54，雾化套1的内壁下部位置对应设有限位凹槽15，限位凸点54嵌入限位凹槽15以将底壳5安装到雾化套1上。优选的，该侧板的外周还设有环状的限位部55，当底壳5安装与雾化套1中时，该限位部55抵接雾化套1敞口处的下侧缘，以提高密封性以及外观整体一致性。结合图3与图5所示，优选地，该进气孔56或导气柱56与导气管13同轴，第一通孔412与第二通孔413分别位于导气管13所在轴线的两侧，由此，进气孔56、第一通孔412、第二通孔413、气流腔与导气管13配合形成大致为双C型结构的气流通道，以将气溶胶导出出气孔11。可以理解的，该气流通道大致为双C型结构，其可以更好地将气溶胶带到用户口中，减少炸油情况。
